Kaniva news reports Alani Afu, 49, also known as Alani Koloamatangi was extradited from the kingdom yesterday over the stabbing murder of the Sydney woman.
He will appear in court on Tuesday for the first day of the committal hearing against his co-accused, the late Ms Caleo’s husband Mark Caleo and his brother Gerard Caleo.
One of his sisters has accompanied him from Tonga and sat in the back of the court today as her brother appeared via videolink from Surry Hills Correctional Centre, Telegraph reported.
Police alleged Ms Caleo, 39, was stabbed multiple times as her two children slept in her Double Bay home on August 10, 1990.
Her 36-year-old brother, Michael Chye, was fatally shot three times just under a year earlier as he drove into the garage of his Woollahra home. He died on October 16, 1989.
The case was reopened in 2011, and two men remain before the court after being arrested by detectives in 2014 and 2015.
Following further investigations, police identified another man and will allege he was involved in Ms Caleo’s murder.
ʻAlani remains at Surry Hills Police Station, where he is expected be charged with murder.
Police have alleged that Ms Caleo’s murder was organised by Mark and Gerard Caleo and carried out by Afu after a multi-million property deal with Mr Chye went wrong.
